After drawing flak for the premature termination of its lunar mission Chandrayaan-1, the Indian Space Research Organisation (ISRO) announced the successful launch today of Oceansat-2 on its 16th flight from the Satish Dhawan Space Centre in Sriharikota, Andhra Pradesh.

ISRO's Polar Satellite Launch Vehicle, PSLV-C14 successfully launched the 960 kg Indian remote sensing satellite Oceansat-2 and six nano satellites into the polar sun synchronous orbit for international customers, ISRO sources said.

This was the 15 th successful flight of PSLV. Oceansat-2 is India's second remote sensing satellite in the series that will study the ocean atmosphere. It replaces Oceansat-1 launched in 1999.

The 960 kg main payload, Oceansat-2, was the first satellite to be injected into orbit after lift-off at an altitude of 728 km. Seconds later, four of the six nano satellites were separated in sequence.

Oceansat-2 is India's 16 th remote sensing satellite of India. The cuboid shaped satellite carries three payloads and has two solar panels projecting from its sides.

The eight band Ocean Colour Monitor (OCM) payload carried by Oceansat-2 images a strip of land or ocean (swath) of 1420 km width with a resolution of 360 metre and works in the visible and near infrared region of the electromagnetic spectrum, the sources added.

Soon after separation from PSLV fourth stage, the two solar panels of Oceansat-2 were automatically deployed.

The mission carried six nano satellites — Swiss 'Cubesats' 1, 2, 3 and 4 and German 'Rubin' 9.1 and 9.2 — as auxiliary payloads.
